AB  - Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion behaviour of these composite structures were characterized by Vickers microindentation test. The dependence of composite microhardness and film adhesion on the structure of the film and mixing conditions of electrolyte were analysed. Mathematical models of Chicot-Lesage and Chen-Gao were applied to experimental data in order to obtain the film hardness and adhesion parameter respectively. It is confirmed that the mechanical properties of composite systems of nickel thin films on silicon substrate can be enhanced by formation of multilayer film structure by ultrasound-assisted electro-deposition and by reducing the layer thickness in the multilayer film.
AB  - Formirani su kompozitni sistemi od jednoslojnih i višeslojnih filmova nikla elektrohemijski deponovanih sa i bez ultrazvučnog mešanja na pločicama od monokristalnog silicijuma orijentacije (100). Tvrdoća i adhezija tih kompozitnih struktura su okarakterisane testom mikrotvrdoće po Vikersu. Analizirana je zavisnost mikrotvrdoće kompozita i adhezije filma od strukture filma i uslova mešanja elektrolita. Matematički modeli Šiko-Lezaža i Čen-Gaoa su primenjeni na eksperimentalne podatke kako bi se dobile vrednosti tvrdoće filma i parametra adhezije. Potvrđeno je da se mehanička svojstva kompozitnih sistema sastavljenih od tankih filmova nikla na silicijumskoj podlozi mogu poboljšati formiranjem višeslojne strukture filmova, primenom ultrazvučnog mešanja pri elektrodepoziciji i smanjenjem debljine sloja u višeslojnom filmu.

AB  - Alternate electrodeposition of ordinary and ultrasonic-assisted Ni layers on polycrystalline copper substrates and single-crystal (100)-oriented silicon wafers was used for the formation of composite systems with nickel thin multilayer films. The hardness and adhesion properties of these composite systems were characterized using Vickers microhardness test, with different loads. Dependence of composite microhardness and film adhesion on type of substrate and layer thickness was investigated. Model of Korsunsky, Chicot-Lesage and Chen-Gao were chosen and applied to experimental data for obtaining the film hardness and adhesion evaluation, respectively. It is confirmed that in comparison with the conventional electrodeposited Ni films, the mechanical properties of the ultrasonic-assisted multilayer Ni films are improved. The microhardness and adhesion of the films are enhanced by introduction of ultrasound and by reducing the layer thickness in the film.

AB  - Multilayer composite structures of electrodeposited Ni films on polycrystalline copper substrates were fabricated with the assistance of ultrasonic agitation. Alternate ordinary and ultrasonicassisted electrodeposition of Ni layers allowed the formation of laminated films. The adhesion and hardness properties were characterized using bidirectional bending test and Vickers microhardness test with different loads. Dependence of composite microhardness and film adhesion on layer thickness was investigated. It was confirmed that densified parallel interfaces give rise to high hardness and strength of composites. Model of Korsunsky was chosen and applied to experimental data for obtaining the film hardness and model of Chen-Gao was applied for the adhesion evaluation. Compared with the conventional electrodeposited Ni films, the mechanical properties of the ultrasonic-assisted multilayer Ni films are improved. The microhardness and adhesion of the films are enhanced by introduction of ultrasound and by reducing the layer thickness in the film.
AB  - Višeslojne kompozitne strukture su sačinjene od elektrodeponovanih filmova Ni na supstratima od polikristalnog bakra uz pomoć ultrazvučnog mešanja. Naizmenična elektrodepozicija slojeva Ni bez i uz pomoć ultrazvučnog mešanja omogućila je formiranje laminatnih filmova. Adhezija i tvrdoća su okarakterisane ispitivanjem na savijanje u dva pravca i Vikersovim testom mikrotvrdoće sa različitim opterećenjima. Zavisnost kompozitne mikrotvrdoće i adhezije filma od debljine sloja je ispitana. Potvrđeno je da veliki broj međuslojnih granica doprinosi povećanju tvrdoće i jačine kompozita. Za obradu eksperimentalnih podataka su odabrani i primenjeni model Korsunskog za izračunavanje tvrdoće filma i model Čen-Gao za procenu adhezije filma. U poređenju sa filmovima Ni elektrodeponovanim na konvencionalan način, mehanička svojstva filmova elektrodeponovanih u prisustvu uzltrazvuka su poboljšana. Vrednosti mikrotvrdoće i adhezije su povećane uvođenjem ultrazvuka i smanjenjem debljine pojedinačnog sloja Ni u filmu.
